Properties-file with a relative path...

Question

Hello everybody,
my question is as follows:
I have a directory-structure like below:
root_dir
|
-- source
|
-- classes
|
-- libs
|
-- xmlfiles
|
myproperties.propsIn words: my root_dir (is actually a subdirectory in my fs) contains folders like source (java-files), classes (class-files)... and a properties-file myproperties.props. The source-dir has subdirs like com/xyz/bla/Mainclass.java...
I want to load the properties-file from the main-class, but without using the absolute path. That's the way I do it at the moment:
Properties props = new Properties();
props.load(new FileInputStream("d:\\foo\\something\\root_dir\\myproperties.props"));But I don't want to write the whole path, because of portability (forget the \\ :) )!
How can I obtain the root_dir?
Thanx for helping!
Regards, Robert4

Well I was already working on a replacer for /../ stuff before I was pointed to the File class. Not the best code I've written, but works fine. Perhaps it could be of use to you.
    public void setCoordinatesFileURL(String coordFileURL)
        coordinatesFileURL=coordFileURL;
        //replace .. to get canonical path
        StringTokenizer st = new StringTokenizer(coordinatesFileURL,"/");
        String[] stringURL= new String[st.countTokens()];
        int teller=0;
        while(st.hasMoreTokens())
            String token=st.nextToken();
            if(!token.equals(".."))
                stringURL[teller]=token;
                teller++;
            else
                teller--;
        coordinatesFileURL="";
        for(int i=0; i<teller-1;i++)
            coordinatesFileURL+=stringURL[i]+"/";
        coordinatesFileURL+=stringURL[teller-1];
    }
